摘要: 制备了用于分离C60和C70的2,4,6-三硝基苯酚改性锆铝复合氧化物高效液相色谱固定相,考察了流动相中甲苯的含量、柱温及流速对C60和C70分离的影响,同时比较了酸腐蚀前后锆铝复合氧化物基质对分离的影响.结果表明,2,4,6-三硝基苯酚改性酸腐蚀后锆铝复合氧化物填料对富勒烯表现出较强的分离能力,具有作为富勒烯制备分离的潜力.

Abstract: The zirconia-alumina composites, prepared by means of sol gel process, were modified with 2, 4, 6-trinitrophenol and used as π-acidic stationary phases for the separation of C60and C70. The influence of the mobile phase(toluene-cyclohexane) composition, the column temperature and the different flow rates on the separation of C60and C70was examined. At the same time, the effect of the composites, which were treated and untreated with nitric acid, on the separation was also investigated. The results show that the acid-treated zirconia alumina composite, after being modified with 2, 4, 6-trinitrophenol, exhibits advantage in the separation of C60and C70, and is a potential packing material for separation of fullerenes in preparation scale.

Key words: High performance liquid chromatography, Modified zirconia alumina stationary phase 2,4,6 trinitrophenol, Fullerenes
